shell commands for finding and deleting duplicate files based on md5sum of the file

This will find all the duplicate photos in a `raw_photos` directory.
create md5sum of all files (after `brew install coreutils`):
find raw_photos -type f -exec gmd5sum "{}" + > files.md5
then sort that and you can find the files where the md5sum (the first field) is repeated for spot-checking and comparison

1. Separation of immutable and mutable logic

Quite a lot of different people have been on the same trail of thought. Gary Bernhardt's formulation of a "functional core, imperative shell" seems to be the most voiced.

"Boundaries" - Gary Bernhardt

"Imperative shell" that wraps and uses your "functional core".. The result of this is that the shell has fewer paths, but more dependencies. The core contains no dependencies, but encapsulates the different logic paths. So we’re encapsulating dependencies on one side, and business logic on the other side. Or put another way, the way to figure out the separation is by doing as much as you can without mutation, and then encapsulating the mutation separately. Functional core — Many fast unit tests. Imperative shell — Few integration tests

Condensed iOS Human Interface Guidelines

Imperatives for AppStore approval

For iPhone app developers. Emphasis on getting the fastest app store approval. Everything stated as suggestion made into an imperative. When "violating" these imperatives, you can check for yourself what the caveats are. Generally speaking, deviating will more likely cause your app to be hung up in approval.

You can read this entire document in about 20 minutes. This is faster than reading and understanding the entire Human Interface Guidelines.

Overview

You can’t perform that action at this time.
